I think you are being a little harsh on KaneIt was a scrappy win, Kane was stood on the exact spot where the ball came to him, scored two absolute sitters and missed every shot that required some control.
!
1st one was ping ball wizard in a very crowded penalty area, and the way he twisted his head for the 2nd to redirect the header near post and also keep / generate more pace on the ball was very well done.
He didn't have that many other chances (I remember one which was saved from him) but Stirling and Lingard did miss some fabulous chances.
